TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 358,469, dated March 1,1887.

Application filed December 19, 1884. Serial o. 150,708. (No model.)

To all whom it may concern.-

Be it known that I, NATHAN Gama Moons, of Peoria, in the county ofPeoria, in the State of Illinois, have invented an Improved Type-Writer; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the annexed drawings,making a part of this specification, in which like letters of referencerefer to like parts, and in which v Figure 2. represents a plan view ofthe same; Fig. 1, a side elevation; Figs. 3, 4, 5, 6, 7, 8, 9, and 10,views of various details of the mechanism.

This invention is in the line of typewriters in which alongitudinally-progressive and laterally-oscillatory roller is adaptedby such movements to press a sheet of paper wrapped thereon againsttypes held in the periphery of a disk, a lever serving not only to turnsaid disk and thereby bring the desired letter in juxtaposition to saidroller, but also, by its downward impression, to oscillate said rolleragainst the type or letter.-

The object of this invention is the effecting of several improvements insuch a type-writer, of which the following are the chief: First, simplerand more effective mechanism for longitudinally shifting the roller andits carriage; second, means for inking the types; and, third, automaticarrangements for revolving the roller.

In the drawings, R is the roller for carrying the paper; 0, the carriagesupporting said roller and adapted to travel longitudinally. O is aframe pivoted to said carriage and con taining the bearings of saidroller.

The types project radially from th e type-disk D, which is adapted'to berevolved in a horizontal plane by means of the lever Ii,pivoted at oneend to the lug L, projecting from said disk and near its center, to theshaft S. The crown D and the letter-circle D, being necessarily fixed inposition, are secured to or formed as a part of the plate F, as shown inFig. 9, which plate is supported by the frame F. The type-disk D, beingmade annular and having its inner diameter fit looselyabout the crown D,rests upon the projecting edge of the plate F, and can be revolvedthereupon, with said crown as a center. The shaft S is loosely held topermit longitudinal movement, and connects at its lower end with anangle-iron, S, by which its vertical motion transmits through theconnecting-rod S the required oscillation to the frame 0 and itscontained roller R.

The crown D is sharply serrated, and the projection P of the lever L ismade terminally V-shaped, that, when said lever is pressed down over anyparticular letter, the sloping sides of said projection and theserration thereat shall cause, when the projection reaches the bottom ofthe serration, the lever to be exactly over the letter, although atfirst it may not have been placed quite true. Then the projection P isrigidly fastened to the lever, the slight movement which said contact ofthe serration and projection gives to the disk D, coming at the sametime with the forward oscillation of the roller B, causes the impressionof the type against the paper to be somewhat blurred. To prevent this, Iadapt the projection P to be vertically movable in the lever L,

having it pressed downwardly by means of the spring P. The neck I of theprojection P is square, to prevent its turning in the lever, and across-pin keeps it from dropping out from its opening in the lever.

The frame 0 is pivoted at O to the carriage O, and is provided with thebuffers O to stop the backward oscillation of the frame 0 and itscontained roller R. Said backward oscillation is given to the frame 0 bythe spiral spring S on the connecting-rod S between the bearing S andthe collar S". To receive a part of the shock of the forward throw ofthe roller It as it comes against the types T, I have constructed thebuffers B, adjustably secured at the ends of the arms B". In front ofeach buffer Bis a spring, B, by which the force of the impact of saidroller is broken- Said arms B To pull the carriage O in one di-" aboutthe wheel J. The wheel J is revolved by means of aspring coiled therein,(not shown in the drawings,) the tension of which is adjusted by meansof the ratchet-wheel J and the pawl J The key-stem J enables the springto be wound up. This wheel J is continually pulling the carriage 0forward. To control this pull and cause the said carriage to progressonly the width of aletter after each printing-stroke, Ihave devised thefollowing construction: A rack-bar, E, is secured to the carriage G bypivots or hinges E. A springcatch, E", keeps the rack-bar down in place.Beneath said rack-bar and meshing therewith is a gear-wheel, G, fast onthe shaft G. Fast on the other end of said shaft is an escapewheel, G".The anchor-escapement H, pivoted at its center to suitable supportsprojecting up from the base-plate or board \V, prevents said escapewheelG from revolving. The pawl H", pivoted in a slot in the shaft S, ispressed within said slot when said shaft is pushed downward. Vhen,however,said shaft is raised,this pawlpushes against the upward end ofthe anchor-escapement H, releases its other end from contact with theeseape-wheel G, and permits said wheel to revolve for the space of onetooth. This distance is arranged to be the required space between eachtwo letters printed by the writer.

To give the space between each two words and wherever else desired, Isupply a lever H", by which, on pressing upon the button H thereof, theescapement H is made to release the wheel G \Vith each distinct movementof said lever the wheel G" moves one tooth and the carriage O is shiftedaccordingly.

My device for inking each type just previously to the impactthereagainst of the paperwrapped roller B, is as follows: The arm Kpivoted at 11*, to a lug projecting from below the plate F carries atits outer extremity a small inking-roller, K, held to said arm byslender springs K. This arm K is thrown upwardly with each downwardstroke of the lever L and the shaft S by the impact against the end K ofsaid arm of the friction-roller K held by the collar K fast on saidshaft S. With the downward stroke of the lever L this arm K is carriedup,theinking-roller K passes up against the type, which has just beenturned thereto, suitably inking it, and is held up above the disk D,while the roller R comes forward against said type. Then as the pressureis removed from the lever Lsaid roller returns and the arm K falls, andthe inking roller K therewith, to its original position. If the weightof said arm is not sufficient to replace it quickly, I design to furnisha suitable spring for aiding such movement.

In order to return the carriage to begin another line, the spring-eatchE is released from the rack-bar E, and the same is raised up out of meshwith the gear-wheel G. The carriage O can then be pushed back to itsinitial position without hinderance. XVhen thus replaced, the rack-bar Eis lowered to again mesh with the gear-wheel G, the spring-catch Ere-engages with the said bar, and the carriage is all ready for its newline. Before beginning the new lineit is necessary, however, to turn theroller B a distance equal to the desired space between the lines. To dothis automatically I have devised the following device:

The lever M, pivoted to the axis of the roller R, has a pawl, M,engaging with the ratchet-wheel R of said roller. Held in bearings N,projecting from the way-bars O, is a triangular plate, N. A spring, N,pressing against the lug N" of said triangular plate, serves to keep thesame in the position shown in Fig. 2. Vhen the lever M travels alongwith the carriage in the working-passage, said plate N is simply pushedout of the way by the end of said lever; but when the carriage isreturned to begin a new line the lever M slides up on the sloping edgeof the plate N, is raised, and the pawl of the lever M caused to engagewith a new notch in the ratchet-wheel B. As the pawl passes the plateNand drops down beyond the same, being pulled by the spring M the rollerR is given the desired lineal change. In place of said plate N, Isometimes use the modification thereof shown in Fig. 7.

Instead of swinging horizontally, my new plate N is adapted by thehorizontal axis N" to swing in a vertical plane parallel with the rollerR. Thelower half of this plate N", being weighted at N, as thepaper-roller R is returned for a new line, the lever M comes in contactwith the edge thereof, and is of course raised in order to pass it. Thisraising of the lever M, as previously described, enables its pawl toengage with a new ratchet-tooth of the ratchet-wheel B. To enable thespring M to give a quick pull to said lever, and thereby a partial turnof the roller, the plate N has a quadrant cut therefrom at N, which outalso enables the said plate to be revolved by the lever when travelingin the opposite direction and to-release said lever without raising thesame.

At the end of the lever L, opposite to the presser-button L, is thefingerL, extending through a slot in the lug L, and terminating justover the edge of the type-disk D. The object ofthis finger is to enablethe types to be adjusted relative to the crown and letter-circle. If,when the projection Pis pressed into a serration of the crown D, a typeis not exactly beneath the end of said finger, it is at once evidentthat a correction is needed. To permit of this adjustment, the type diskD is composed of three thin annular disks, D D and D. D are the outerdisks, to the upper of which the lug L is rigidly attached, while D, theinner disk, is the type-disk proper. Said disk D, I usually form of woodor hard rubber and divide its periphery into the radial notches D, equalin number to the characters which I design the type-writer to have. Byemploying a suitable number of screws, D", to clamp together these disksD, D and D,

and having the screw-holes in the disk D elongated at right angles tothe radii thereat, the said disk D can be evidently revolved somewhatrelatively to the disks D and hence adjusted relative to the lever L andto the letter-circle. Figs. 8 and 9 show this arrangement of thetype-disk. The disk D, Imake slightly thinner than the types, so thatthe disks D can grip the types sufficiently hard to hold them securelyin place.

I am aware that prior to my invention typewriters have been constructedin which are many of the details shown in the drawings and described inthe specification of this application; hence I do not claim thembroadly; but
